PACKAGE WRAPPING Filed Nov. 3, 1944 6 Sheets-Sheet 6 INVEN TOR. 5/7/ V0225 dames Patented July 5, 1949 UNITED STATES FATENT OFFICE 4 Claims.

This invention relates to packaging and has as its principal aim the provision of a pre-formed package wrapping which may be placed about a package of predetermined size and shape with a minimum amount of effort and labor. This application is a continuation in part of my application Serial No. 425,436, filed Jan. 2, 1942, now U. S. Letters Patent No. 2,365,704 issued Dec. 26, 1944.

Another object of this invention is the design of a package wrapping of the type as aforesaid which shall have a very pleasing and artistic appearance as well as incorporating therein the features above mentioned.

A further aim of this invention is embodied in a pre-formed wrapping with the characteristics described above, which forms a very compact, flat article before the same is placed in position on the package. This aim makes it possible for the article to be shipped and stored in considerable quantities in a small space and lends itself well to counter service.

The invention further contemplates a package wrapping having a unique series of folds, bends and plaits therein whereby the article may be manufactured from an intially flat sheet of paper and assembled to provide a wrapping having reinforced corners and a relatively high degree of structural strength.

This invention further results in an article which may be assembled on the package to be wrapped and secured in place without special tools, string or the usual appurtenances of the wrapping art. The parts of which this invention is comprised, are united and held in position by the structure and means incorporated in the article itself.

It is a yet further aim of this invention to provide wrapping means wherein all the folds thereof that are not made on the outer edges of the package are projected inwardly toward the package. Thus, it is contemplated that all the various areas of the packagetop, side, ends and bottom, will lie closely adjacent the package since the folds on these surfaces project inwardly and not outwardly.

Further aims and objects of this invention will become apparent from the following description thereof, reference being had to the accompanying package wrapping when the same is folded for storage.

Fig. 2 is a perspective view of a form of the package wrapping when the same is partially unfolded preparatory to use thereof.

Fig. 3 is a perspective View of the article to be wrapped.

Fig. 4 is a perspective view of the package wrapping and article to be wrapped, the former being partially in place on the latter to illustrate the means of positioning the wrapping on the article.

Fig. 5 is a perspective View of the wrapping after being positioned on the article.

Fig. 6 is a stretch out view of a form incorporated in a modification of the invention; and Figs. 9, 12, 15, 18, 21, 24, 2'7, 29 and 31 are partial stretch out views of modifications of several forms used in making the wrapping.

Figs. 7, 10, 13, 16, 19 and 25 are perspective views of modifications of the wrappings, when the same are folded for storage, of forms shown in Figs. 9, 12, 15, 18, 21 and 27 respectively.

Figs. 8, 11, 14, 1'7, 20, 23, 26, 28 and 30 respectively, are perspective views of the wrapping, in place on the articles, of forms shown in Figs. 9, 12, 15, 18, 21, 24, 27, 29 and 31 respectively.

Fig. 22 is a perspective view of an article inserted in an adaptor conforming in shape to the configuration of wrapping made in accordance with this invention.

In the species of the invention shown in Figs. 1, to 6 inclusive, is a quadrangular blank having attached thereto, contiguous therewith, and at opposite edges thereof, end walls 42. Adjacent end walls 42 and contiguous therewith, are top walls 44. Crease 43 is formed by creasing wall 42 inwardly along the line of juncture thereof with said blank 40, said line being designated as AA. Turn 45 is formed by turning top wall 44 inwardly at its line of juncture with end walls 42, said line of juncture being designated as BB.

Attention is directed to the fact that all inward turns, creases, etc., are designated by solid lines; where it is necessary to indicate an outward crease, turn, etc., the same will be designated on the drawings by means of a broken line.

Walls 42 and 44 have attached thereto, along the lateral edges thereof, members 46. It is to be noted that Fig. 6 comprises two similar sets of contiguous end and top walls 42 and 44- respectively. Each set has attached thereto along each of its two lateral edges corresponding members 46. The set to the right of the drawing is geometrically similar to the set on the left with the exception of the projections 72 attached to the former. Figs. 9, 12, 15, 18, 21, 24, 2'7, 29 and 31 respectively, are partial stretch out views showing only a portion of blank 40, and a single set of side and end walls; thus only one top wall 44, one end wall 42, and two members 46 are shown in each of the aformentioned figures. In each set the members 46 are correspondingly folded and positioned, so for the sake of simplicity, the speciflcation will describe the folding and positioning of but a single member 46, or parts 48 and portions 56corresponding thereto found in the several modifications.

It is to be understood that each of the re' spective side walls 56 (Figs. 5 and 8) are formed in an identical manner by means of corresponding elements. I

The line of juncture between walls 42, and member 46 is designated by line AC, said member 46 being plaited inwardly from walls 42 and 44 to form plait 41. Member 46 is bent outwardly along the transverse median line BD thereof, the bend 49 being contiguous with. but opposed to the fold 45 along line BB; the intersection of said fold 45 and said bend 49 being designated point B. The outward bend 49 of member 46 along line BD serves to divide member 46 into a quadrangular part 48 and a quadrangular portion 50- the part 48 being adjacent the end 42 and the portion 50 being adjacent the top 44.

Part 48 and portion 58 have opposed diagonal fiexions 5| and 53 extending to the free corners of member 46 from point B, the same being made on lines EB and FE of part 48 and portion 50 respectively.

The flexing of portion 50 inwardly, and the flexing of part 48 outwardly along the lines PB and EB respectively is continued until the corresponding areas 52 and 54 bordered by the lines EDB and FDB respectively, are in contact engagement.

When member 46 is positioned as above described, walls 42 and 44 will be at right angles to one another, and side walls 56 will be formed from member 46. Areas' 52 and 54 are secured together at the outward corners thereof, at the vertexes of angles BED and BFD respectively, by means of adhesive 58. This adhesive is on the outside of form 38 as shown and is adapted to secure together areas 52 and 54 as aforesaid.

The placing of adhesive 58 on the outside of form 38 is indicated by means of the broken patch lines, as shown in the drawings. The placing of adhesive on the inside 62 of form 38 is indicated by means of the unbroken patch lines.

Thus cover sections 64 are formed, being hingedly joined toblank 48 by means of corresponding creases 43 formed at the junction of side walls 42 with blank 40 along lines AA. The package '66 to be wrapped is then placed squarel on blank 40 and the angular sections '64 are moved to position in such manner that package 66 is covered.

Flaps 68 are joined to the other opposite sides of blank 40 along lines AA and A'A' respectively. These flaps are contiguous with blank '40 and are platit'ed inwardly at the line of junction therewi h.

Flaps 68 carry on the free marginal edges thereof gum mixture 10 which may be rendered adhesive by moistening the same. These flaps 68 are then positioned in contact with sides 56 after said gum mixture has been mo stened. Thus, the opposed cover sections 64 are fixemy secured in place. In order that these sections 64 may be secured more firmly, D jections 1 2 have "gum mixture thereon and the same will serve to attach said projections 12 to adjacent top wall 44 and side walls 56. Gum mixture 10 is placed on the 4 inside of form 38 and is designated by means of stippling in the drawing.

Folding the material from which sides 56 are formed, outwardly along the several solid lines and inwardly along the dotted or broken lines shown in the drawings and particularly Fig. 6, and securing together the adhesive-carrying portions, will create collapsed side, top and end walls that are flat in character. When extended to receive the package 66, the walls are angular as shown in Figs. 2 and 4.

Thus, it is readily seen that the invention comprises two end sections 56 made as aforesaid, and that these end sections are corresponding in all details except the fact that projections 12 are attached to only one section.

In order that the package wrapping will fold fiat as shown in Fig. 1, it has been necessary to incorporate an outward crook 63 in each cover section 64, said crook 63 being formed along line GG' which is the median line of end 42. An inward wrinkle 65 at HG and an outward wrinkle 61 at HI are formed in member 46 after part 48 and portion 50 are in assembled relationship. When the elements forming end 56 are folded into compact relationship, wall 42 is folded back upon itself along lines GG', and area E, A, H, I, and area D, B, H, I, will lie in corresponding positions, said areas extending in the same direction as top wall 44 and co-terminal with the width thereof. The entire flat section 13 thus folded is creased over along line AA whereby said sections 73 will overlap and be co-extensive with blank 48. Flaps 68 are then folded inwar'dly over the previously folded section 13 to form a flat package as shown in Fig. 1.

Figs. '7, 8 and 9 illustrate another modification of the invention. In this modification Fig. 9 shows a portion of a quadrangular blank 40 having attached thereto, contiguous therewith, and at the opposite edges thereof, end walls 42. Adjacent end walls 42 and contiguous therewith are top walls 44. Crease 43 is formed by creasing wall 42 inwardly along the line of juncture thereof with said blank 46, said line being designated as AA.

Turn 45 is formed by turning top wall 44 inwardly at its line of juncture with end walls 1432, said line of juncture being designated as A part 48 and a portion 58 lie along the transverse edges of walls 42 and 44 respectively. The line of juncture between walls 42, 44 and part 48 and portion 58 is designated by line AC, said part 48 and portion 50 being plaited inwardly from walls 42 and 44 respectively to form plait 41. Top wall 44 is turned along turn 45 until it is at right angles with wall 42. Portion 50 will then overlie the area EDB on the outside of part 48. Part 48 and portion 56 are then secured together in this position by means of adhesive 58. This adhesive 58 is placed on the outside 68 of part 48 and on the inside 62 of portion 50, as shown in the drawings. Thus cover section 84 is formed having an end wall 42, a top wall 44 and a side wall 56, said cover section being hingedly joined to blank 40 by means of crease 43 formed at the junction of side walls 42 with blank 40 along lines AA. After each section has been made in the aforesaid manner, the package 66 to be wrapped is placed squarely on blank 48 and sections 64 are posit1oned in such manner that package 66 is covered. v Flaps 68 are joined to the other opposite sides of blank 40 along lines AA and A'A respectively. These flaps are contiguous with blank 40 and are plaited inwardly at the point of junction therewith. Flaps 68 carry on the free marginal edges thereof gum mixture it which may be rendered adhesive by moistening the same. These flaps 63 are then positioned in contact with sides 56 after said gum mixture has been moistened. Thus, the opposed cover sections 64 are fixedly secured in place. In order that these sections 64 may be secured more firmly, projections 12 have gum mixture thereon and the same will serve to attach said projections I2 to adjacent top Wall 44 and side Walls 56.

In order that this package wrapping will fold flat as shown in Fig. 7, it is necessary to incorporate an outward crook 63 in each cover section 64, said crook being formed along line GG, which is the median line of end 42. An inward wrinkle 65 at HG and an outward wrinkle 6? at HI are formed in wall 5&5 after superimposed portion 50 and part 46 are in assembled relationship.

When the elements forming end 56 are folded into compact relationship, wall 42 is folded back upon itself upon line GG and area EAHI and area DBHI will lie in corresponding positions, said areas extending in the same direction as top wall and co-terminal with the width thereof. The entire fiat section 12 thus folded is creased along lines AA whereby said section i2 will overlap and be co-extensive with blank 46. Flaps B6 are then folded inwardly over the previously folded section 72 to form a flat package as shown in Fig. '7.

Figs. 10, 1i and 12 illustrate a modification of the invention. In this modification Fig. 12 shows a quadrangular blank 46 having attached thereto contiguous therewith, and at opposite edges thereof, end walls 42. Adjacent end walls 42 and contiguous therewith are top walls 44. Crease is formed by creasing wall 42 inwardly along the line of juncture with said blank 49, said line being designated as AA.

Turn 4% is formed by turning top wall 44 inwardly at its line of juncture with end walls 42, said line of juncture being designated as BB. A member is formed along the transverse edges of walls and 44. The line of juncture be tween walls 42, 44 and member 46 is designated by line AC, said member 46 being plaited inwardly from walls 42 and 44 to form plait 47.

Member 45 is bent outwardly along the transverse median BD thereof, said bend 49 being contiguous with but opposed to the fold 45 along line BB'-the intersection of said fold and said bend being designated as point B. The outward bend 49 of member 46 along line BD serves to divide member 46 into a quadrangular part 48 and a quadrangular portion 56--the part 46 being adjacent the end 42 and the portion 56 being adjacent the top 44.

Part 43 and portion 59 have opposed diagonal fiexions 5i and 53 extending to the free edges of member from point B, the same being made on lines EB and FE of part 48 and portion 56 r spectively. The flexing of portion 54 inwardly and the flexing of part 48 outwardly along the lines FE and EB respectively is continued until the corresponding areas 52 and 54 bordered by the lines FDB and FDB respectively are in contact engagement.

When member 46 is positioned as above described, walls 42 and 44 will be at right angles to one another, and side walls 56 will be formed from member 46. Areas 52 and 54 are secured together at the outward corners thereof at the vortexes of angles BED and BFD respectively, by

means of adhesive 58. This adhesive is placed on the outside 60 of form 38 as shown in Fig. 12 and when so positioned, will be adapted to secure areas 52 and 54 in engagement as aforesaid.

Flaps 68 are joined to the opposite sides of blank 46 along lines AA and AA respectively. These flaps are contiguous with blank 46 and are plaited inwardly at the point of junction therewith. Between each of said flaps 66 and member 46 is a quadrangular piece '14. This piece '14 has a free edge 16 co-extensive and adjacent flap 68 on line WY. Piece 14 is contiguous with flap 68 on line AY and with member 46 on line AX, the same being crimped outwardly at the line of connection AX with the said member 46 and inwardly at the line of connection AY with the said flap 68. Thus, side walls 56 are formed having the reinforcing piece 14 adjacent thereto. The package 66 to be wrapped is placed squarely on blank 46 and sections 64 are positioned in such manner that package 66 is covered. Flaps 68 are secured to the sides 56 of the package wrapping in the same manner as hereinbefore described, in connection with the previous forms.

In order that the package wrapping will fold flat as shown in Fig. 10, it is necessary to incorporate an outward crook 63 in each cover section 64, said crook being formed along line GG', which is the median line of end 42. An inward wrinkle 65 at HG and an outward wrinkle 61' at HI are formed in member 46 after part 48 and portion 50 are in assembled relationship. When the elements forming end 56 are folded into compact relationship, wall 42 is folded back upon itself along lines GG', and area IHAX and area II-IBD will lie in corresponding position-s, said areas extending in the same direction as top wall 44 and co-terminal with the width thereof. Piece 14 is folded inwardly along crimp YA and outwardly along crimp XA and in such position will lie adjacent flap 68. The entire flat section 12 thus folded is creased over along line AA whereby said section 72 will overlap and be coextensive with blank 46. Flap 63 with the piece 14 inwardly of and adjacent thereto, is then folded inwardly over the previously folded ends '56 to form a fiat package as shown in Fig. 10.

Figs. 13, 14 and 15 illustrate a modification of the invention. In this modification Fig. 15 shows a quadrangular blank 40 having attached therewith, contiguous therewith, and at the opposite edges thereof, end walls 42. Adjacent end walls 42 and contiguous therewith are top walls 44. Crease 43 is formed by creasing wall 42 inwardly along the line of juncture thereof with said blank 44, said line being designated as AA. Turn 45 is formed by turning top wall 44 inwardly at its line of juncture with end walls 42, said line of juncture being designated as BB.

A part 48 and a portion 5!] lie along the transverse edges of walls 42 and 44.

The line of juncture between walls 42, 44 and part 48 and portion '50 respectively, is designated by line AC, said part 48 and said portion 56 being plaited inwardly from walls 42 and 44 respectively to form plait 41.

Top wall 44 is folded inwardly along fold 45 until part 48 and portion 50 overlap. The inside of part 48 is covered with adhesive 56 and the outside of portion 56 is covered with adhesive 58thus the said surfaces of part 48 and portion 50 may be joined together by means of adhesive 58 to form a side wall 56.

Quadrangular piece 14 lies between flap 68 and part 48 and has two of its sides contiguous therewith. Piece-l4 has a free edge 16 adjacent to a portion of 'fi'ap 68 on line AY. Piece M has an inward crimp AY and an outward crimp AX at the lines of juncture with flap 68 and part 58 respectively. The package 66 to be wrapped is positioned on blank 40 and sections (54 are positioned in a manner as hereinbefore described in connection with the above modifica tions.

Flaps 68 have gum mixture H! at the free marginal edges thereof for securing the flaps to side walls 56 as hereihbeiore described. When flaps 68 are in operative position, piece 14 is folded thereagainst and between the flaps B8 and said side wall 56, thus serving to reinforce the wrappin-g.

In order to fold the package wrapping fiat as shown in Fig. 13, it is necessary to incorporate an outward crook (53 in each cover section 64, said crook being formed aiohg line GG', which is the median line of end 4-2. An inward wrinkle $5 at HG and an outward wrinkle 6-? at HE are formed in part 5% and portion 553 respectively when the same are in assembled relationship.

When the elements forming end 56 are folded into compact relationship, wall '42 is folded back upon itself along lines 'GG, and area EHAX, an area EHBD will lie in corresponding positions, said areas extending in the same direction as top wall M and c'o-term-inal with the width thereof.

The entire fiat section l3 thus folded is creased over along lines AA whereby said sections 73 will overlap and be co-extensive with blank 40. Flap 68 with pieces 14 adjacent thereto are then folded inwardly over the previously folded sections 73 to form a'flat package as shown in Fig. 13.

The form of the invention as illustrated in Figs. 16, 17 and i8 is exactly the same as the form illustrated in Figs. 13, 14 and with the exception that lines FC, AC, XF, FC', A'C, XF' are tapered inwardly whereby said wrapper when assembled as described in connection with Figs. 13, 14 and 15, may be constructed to accommodate a container having larger dimensions at its top than at its bottom. Such container, as shown in Fig. 17, has a teles'coping lid 18 which increases the dimensions of the top of the box and necessitates the use of this form of taper.

Edges DB and DB are cut at an angle to establish a taper of a degree required by the angularity just above mentioned. Mani'festly these angles are determined by the lid '18 and remaining portion of the container. Likewise the shape of portions 50 maybe altered at FC and FC' to better accommodate an article of a particular shape.

Figs. 19, 20 "and 21 illustrates another modification of the invention wherein is a quadrangular blank having attached thereto, contiguous therewith, and at the opposite edges thereof, end walls 12. Adjacent end walls are top walls M. Crease 43 is formed by creasing wall 42 inwardly along 'the lin'e of juncture thereof with said blank '40, said line being designated as AA.

Turn 45 is formed by turning top 'wall "M inwardly at its line or juncture with end walls 42, said line of juncture being designated as BE.

A member 46 lies along the transverse edges of walls 42 and W4. tween walls 42, M and member 46 is designated by line AC, said member '46 being p'l'aited inwardly from walls 42 and '44 to form -plait 41. Member 46 is bent outwardly along the transverse median BD thereof, This means B12 c2;-

The line of juncture betends along the line or greatest Width of member 86-. (Jo-extensive with line B!) is the width of member 46 along lines GI and FZ. Member 2'6 is bent outwardly along the transverse median BD thereof, said bend 49 being contiguous with but opposed to the turn 45 along line BB; the intersection of said turn 45 and said bend 49 being designated as point B. The outward bend 119 of member 46 along line BD serves to divide member 46 into a polygonal part '48 and a polygonal portion 5!). Part 48 and portion 50 have opposed diagonal fle'xion's 5'4 and 53 extending to the free edges of member 46 from point B to points K and L respectively; said flexions being made on line KB and LB of part 48 and por- 'tion 5!} respectively. The flexing of portion 50 inwardly and the flexing of part '48 outwardly along lines LB and KB respectively, is continued until the corresponding areas 52 and 5 1 bordered by lines IKBD and FLBD respectively, are in contact engagement.

This wrapper accommodates a container having larger dimensions at its top than at its bottom when the angles IKX, FLS, I'KX' and F'LS' are greater than as shown, and the shape of part 48 and portion "50 are altered as described in connection with Figs, 1T5, 1'7 and 18. The angles are substantially as shown whereby the wrapper will fit an article of the shape shown in Fig. 20.

When member @6 is positioned as above described, walls 42 and 44 will be at right angles to one another and side Walls 56 will be formed from member 46. Areas 52 and 54 are secured together by meansoi adhesive 58 placed on the outside '68 of form 38 as shown in Fig. 21. Thus, cover sections '54 are formed being hingedly joined to blank 40 by means of corresponding creases 43 formed at the junction of side walls 42 with blank 40 along line AA.

Flaps 68 are joined to the opposite sides of blank it and are contiguous therewith. These flaps are p'laited inwardly and positioned in the same manner as described in connection with the previous forms.

In order that the package will fold flat as shown in Fig. "19, it has been necessary to incorporate an outward crook 53 in each cover section 44, said crook (5'3 being formed along line 'GG', which is the median line of end 42. An outward wrinkle '65 at KG is for-med in memher it after part '48 and portion 59 are in assembled relationship. When the elements forming end 55 are folded into compact relationship, wall 42 and member 56 are folded back upon themselves respectively along lines GG', GK and GK'. Flaps 68 are then folded inwardly over form 40. The enti-r'e flat section 13 is creased over along line AA whereby said section '13 will overlap blank '40 and. flaps 68.

The form of invention as illustrated in Figs. 22, 23, and 24 is similar in the essentials of construction to the form shown inFigs. 1-3, 14 and 15, however, this form is especially designed to be used with an irregularly shaped package having an adaptor of specified dimensions placed thereon. Where round objects and the like are to be wrapped, it is "a practice of the trade to place about said irregular package, a hollow, squarecorn'ered adaptor in order to facilitate the wrappingof the article.

This adaptor "89 and irregularly shaped article 32 are sh wn iii! Fig, 22 with the article placed within the adaptor and a portion of the adaptor broken to more clearly reveal article 82.

Fig. 23 shows the wrapping in place on the adaptor but with flap 68 in an extended position before the same has been sealed in order to reveal an opening 84 in the wrapping through which the article 82 may be positioned within adaptor 84.

In this modification, form 38 has been out so that when folded, openin 84 will be present therein, and further, the corners will be reinforced with a double thickness of material so as to better retain article 82 in place.

Fig. 24 shows a blank similar to that in Fig. 15, but the exterior free corners of part 48 and portion 50 have been removed therefrom; the length of quadrangular piece 14 being the same as the shortest dimension of part 48 along line XA.

Part 48 and portion 58 are positioned, folded, etc. in the same manner as part 48 and portion 58 of Fig. 15. The package wrapping may be folded flat in the same manner as illustrated in Fig. 13.

Figs. 25, 26 and 27 illustrate another modification of the invention. In this modification, Fig. 27 shows a quadrangular blank 48 having attached thereto, contiguous therewith, and at the opposite edges thereof, end walls 42. Adjacent end walls 42 and contiguous therewith are top walls 44.

Crease 43 is formed by creasing wall 42 inwardly along the line of juncture thereof with said blank 40, said line being designated as AA. Turn 45 is formed by turning top wall 44 inwardly at its line of juncture with end walls 42, said line of juncture being designated as BB.

A part 48 and a portion 50 lie along the transverse edges of walls 42 and 44 respectively. A line of juncture between walls 42, 44 and part 48 and portion 58 respectively, is designated by line AC, said part 48 and portion 58 being plaited inwardly from walls 42 and 44 respectively to form plait 41. Top wall 44 is turned along turn 45 until it is at right angles with wall 42. Portion 58 will then overlie area IHBD on the outside of part 48. Part 48 and portion 50 are then secured together in this position by means of adhesive 58. The adhesive 58 is placed on the outside 80 of part 48 and on the inside 62 of portion 50, as shown in the drawings-thus, cover section 64 is formed having an end wall 42, a top wall 44 and a side wall 58,*said cover section being hingedly joined to blank 40 by means of crease 43 formed at the junction of the side walls 42 with blank 49 along line AA.

After each section 64 has been made in the aforesaid manner, the package 56 to be wrapped is placed squarely on blank 4!] and sections 64 are positioned in such manner that the package 66 is covered.

Flaps 58 are joined to the opposite sides of blank 48 alon line AA and AA respectively. These flaps are contiguous with blank 48 and are plaited inwardly at the point of junction therewith. Flaps 58 carry on the free marginal edges thereof, gum mixture in and are positioned by means thereof as hereinbefore previously described. In order that section 64 may be secured more firmly, projections 12 have gum mixture thereon and the same will serve to attach said projection 12 to adjacent top wall 44 and side walls 56.

This wrapper accommodates a container having larger dimensions at its top than at its bottom When the shape of part 48 and portion 50 is as shown in the drawing and described in connection with Figs. 16, 17 and 18.

In order that this package wrapping will fold fiat as shown in Fig. 25, it is necessary to incorporate an outward crook 63 in cover section 64, said crook being formed along line GG', which is the median line of end 42. An outward wrinkle at HG and HG' is formed in wall 56 after superimposed portion 50 and part 48 are in assembled relationship.

When the elements forming end 55 are folded into compact relationship, wall 42 is folded back upon itself upon line GG. The entire fiat section 73 thus formed, is creased along line AA. Flaps 68 are then folded inwardly and section 13 superimposed over the said flaps 68.

Figs. 28 and 29 illustrate a modification of the invention. This modification in Fig. 29 shows a quadrangular blank 40 having attached thereto and contiguous therewith and at the opposite edges thereof, end walls 42. Adjacent end walls 42 and contiguous therewithare top walls 44.

Crease 43 is formed by creasing wall 42 inwardly along the line of juncture with said blank 48, said line being designated AA. The turn 45 is formed by turning top wall 44 at its line of juncture with end walls 42, said line of juncture being designated as BB.

An L-shaped member 46 is formed along the transverse edge of walls 42 and 44. The line of juncture between walls 42, 44 and member 46 is designated by line AC, said member 46 being plaited inwardly from walls 42 and 44 to form plait 41.

Member 46 is bent outwardly along line DB thereon, said line being contiguous but opposed to the turn 45 along line BB; the intersection of said turn and said bend being designated as point B. The outward bend 49 of member 45 along line BD serves to divide member 46 into a slotted part 48 and a portion 5!], part 48 being adjacent end 42 and portion 50 being adjacent top 44.

Portion 59 has therein an inwardly flexed diagonal fiexion 5| along line FB. The bending of portion 50 outwardly on bend 49 and the flexing of portion 58 inwardly on flexion 5! is continued until the outside of areas XDB and FDB are in overlying contact engagement, the said areas being secured together by adhesive 58. When the said above areas are positioned as stated, area FBGE of portion 5! 1 will overlie the outside of area SBGH of part 48 and the inside of area DFB of portion 50. These areas are also secured together by means of adhesive 58.

Because of slot XI in part 48 area XIA is free to be folded over inwardly along line AI until it overlies area AIB and is secured thereto by means of adhesive 58.

When the entire member 46 has been positioned as above described, walls 42 and 44 will be at right angles to one another, and cover sections 64 are thereby formed.

The package 66 to be wrapped is placed on blank 49 and sections 54 are positioned in such manner that package 66 is covered. Flaps 88 are secured to the sides of the package Wrapping in the same manner as hereinbefore described.

In order that this package wrapping will fold fiat, it is necessary to incorporate an outward crook B3 in cover section 84, said crook being formed along line LL which is the median line of end 42. An inward Wrinkle 6t; at IL and IL is formed in wall 56 after superimposed portion 54 and part are in assembled relationship.

When the elements forming end 56 are in assembled relationship, wall 42 is folded back upon itself upon line GG' and superimposed portions 58 and parts 48 are plaited inwardly on B0 and 3'0" until they are adjacent top wall 44. Superimposed areas XIA and AIB are wrinkled inwardly on IL and TL and plaited inwardly on AB and AB' until they overlie end wall 42. The entire flat section 13 thus formed, is creased along line AA. Flaps 68 are then folded inwardly over sections 13.

Figs. 30 and 31 illustrate a modification of the invention which is similar to the modification shown in Figs. 10, 11 and 12, however, this modification is like the preceding modification which is especially well adapted to be used in Wrapping thin flat packages.

In this modification Fig. 31 shows a quadrangular blank 46 having attached thereto, contiguous therewith, and at opposite edges thereof, end walls 42. Adjacent end walls 42 and contiguous therewith are top walls 44. Crease 43 is formed by creasing we the line of juncture with said blank 46, said line being designated as AA. Turn 45 is formed by turning top wall 44 inward-1y at its line of juncture with end walls 42, said line of juncture being designated as BB. I v M A member 46 is formed along the transverse edges of walls 42 and 44. The line of juncture between walls 42, 44 and member 46 is designated as line AC, said member 46 being plaited inwardly from walls 42 and 44 to form plait 41.

Member 46 is bent outwardly along line BD thereof, said bend 49 of member 46 along line 131) serves to divide member 46 into a part 48 and a portion Ell part '48 being adjacent end 42 and portion 50 being adjacent top 44. Part 46 and portion 50 have opposed diagonal fie'xions i and 53 extending to a slit B8 in member 46 from point B, and to slot 96 of member 46, the same being made on lines EB and FE of part 48 and portion 56 respectively. The flexing of portion 56 inwardly and the flexing of part 48 outwardly along the lines EB and PB respectively is continued until the corresponding areas 52 and 54 lying within lines 'EDB and FDB respectively, are in contact.

When member '46 positioned as above described, walls 42 and 44 will be at right angles to one another and side walls 66 will be formed from member 46. Areas 52 and 54 are secured together near the outward corners thereof by means of a tongue 92 and a tongue 94 at the edges of part 48 and portion 56 respectively, as shown in Fig. 31.

Flaps '68 are joined to the opposite sides of blank 4t along lines AA and A'A respectively. These flaps are contiguous with blank 46 and are plaited inwardly at the point of junction therewith. Between each "one of said flaps 68 and said member 46 is a quadrangular piece 14. This piece 14 has a free edge 16 adjacent a free edge of flap 68 on line WY. Piece 14 is contiguous with flap 68 on line AY and with member 46 on line AE; being crimped outwardly at the line of connection AX with said member 4 6 and inwardly at the line of connection AY with the said flap 68. Thus 'co'ver'sections 64 are formed having the reinforcing piece 14 adjacent thereto. The package 66 to be wrapped is placed on blank 40 and sections 64 a-'re positioned in such manher that package 66 is covered. 'F1ap's 68 are secured to sides 56 cf the package wrapping in the same manner as hereinbefore described in connection with the previous forms.

In order that the wrapping will fold flat as shown in connection with Fig. 10, it is necessary to incorporate an outward crook 63 in eachcover lls 42 inwardly along section 64, said 'crook being formed along line GG' which is the median line Of end 42. An inward wrinkle 64 at EG and an outward wrinkle 6'! at HE are formed in member 46 after part 46 and portion 56 are in assembled relationship.

When the elements forming side 56 are folded into compact relationship, wall 42 is folded back upon itself along line GG and area EXA will be superimposed over area HEBD. Piece 14 is folded inwardly along crimp YA and outwardly along crimp XA and in such position, will lie adjacent flap 68. The entire section 12 thus folded is creased over along lines AA, whereby said section 12 will overlap and be co-extensive with blank 49. Flap 68 with piece 14 inwardly of and adjacent thereto, is then folded inwardly over the previously folded end 10 to form a flat package similar to that shown in Fig. 10.

When the pre-formed package Wrapping is collapsed for shipment and storage prior to application to the package, most of the areas of the wrapping that appear on the outside of the wrapped package, are maintained in a fiat, uncreased condition. These stretches or areas of the Wrapping lie over the main quadrangular blank that is substantially the same size as one sideof the package to be wrapped. Most of the folds permitting the flattened condition of the wrapper, are in the end walls and these end walls are covered in substantially their entirety by the gummed flaps that are drawn up thereover when the pre-formed wrapper is placed around the package to present a smooth face to the package where the creases of the end walls might otherwise present an objectionable appearance. This condition prevails in the form of wrapper illustrated in Figs. 1, '7, 10, 13 and 16.

Where fancy and expensive wrapping material is used to produce the wrapper, the formation of the enveloping case in accordance with the invention herein disclosed, not only reduces the amount of material employed, but insures a neat smooth appearance which, after all, is the prime object of wrapping packages in fancy, expensive paper.
